sorry if this has been posted before, I see posts
here and here
Maybe we could collate issues reagarding speed in this post.
basically I've tried everything, I only get 700k/s , now my machine is separated by 3 internal walls (plaster- not concrete) and a distance of only 4 meters. even when I bring the two boxes closer I only get ~30/94 connection quality max
I use the following commands
(setting up accesspoint)
| Code: |
wlanconfig ath0 create wlandev wifi0 wlanmode ap
iwconfig ath0 rate 54M auto
iwconfig ath0 essid grrr channel 10
iwpriv ath0 mode 3
iwpriv ath0 turbo 1
iwpriv ath0 rts 40
ifconfig ath0 192.168.2.1
ifconfig ath0 up
|
(setting up station)
| Code: |
wlanconfig ath0 create wlandev wifi0 wlanmode sta
iwconfig ath0 rate 54M auto
iwconfig ath0 essid grrr channel 10
iwpriv ath0 mode 3
iwpriv ath0 turbo 1
iwpriv ath0 rts 40
ifconfig ath0 192.168.2.1
ifconfig ath0 up
|
both my cards are Netgear 311T 108Mbps, which should be able to do several MB/s however the rate seems to be only able to do between 5Mbs and 10Mbs, which explains the speed. If I take off auto and fix it to 54Mb/s I get very poor performance and lots of lag, maybe transfers at 13k/s.
I have tried all sorts of setting, and can't get a good speed. The only thing that I can think of is tring to get a higher link quality, but I just cant seem to get abouve 35. Setting txpower seems to have no affect either.
any ideas appreciated.  |

*bump
In my latest effort
I have added the options
| Code: |
/usr/local/bin/wlanconfig ath0 create wlandev wifi0 wlanmode sta
iwconfig ath0 rate 54M auto rts 40 channel 10
iwpriv ath0 mode 3
iwpriv ath0 turbo 1
iwpriv ath0 ar 1
iwpriv ath0 burst 1
iwpriv ath0 bgscan 0
ifconfig ath0 192.168.2.2
ifconfig ath0 up
iwconfig ath0 essid grrr
|
now when I scp I get 1.5 MB/s but quickly drops to 800k/s
for the AP

that's about the most I can get, maybe i need a better ariel on the ap, as it's just using the stock one. I made a custom one for the station out of a dog food can. |
